Eulerian graded -modules
Linquan Ma, Wenliang Zhang
Let be a polynomial ring over a field of arbitrary characteristic and be the ring of differential operators over . Inspired by Euler formula for homogeneous polynomi…
A sufficient condition for F-purity
Linquan Ma
It is well known that nice conditions on the canonical module of a local ring have a strong impact in the study of strong F-regularity and F-purity. In this note, we prove that if…
The category of F-modules has finite global dimension
Linquan Ma
Let R be a regular ring of characteristic p. Hochster showed that the category of Lyubeznik's F-modules has enough injectives, so that every F-module has an injective resolution in…
Finiteness properties of local cohomology for F-pure local rings
Linquan Ma
In this paper, we show that for an -pure local ring $(R,\m)$, all local cohomology modules $H_{\m}^i(R)$ have finitely many Frobenius compatible submodules. This answers positiv…
